YEAGER IOUN'I'ING FOR RADIATORS Filed July 1'7, 1926 3 Sheets-Sheet 5 Patented Sept. 9, 1930 STATES PATENT OFFICE HENRY YEAG-ER, OF BUFFALO, NEW YORK, ASSIGNOR TO FEDDERS MANUFACTUR- ING COMPANY, INC, OF BUFFALO, NEW YORK, A CORPORATION OF NEW YORK MOUNTING FOB RADIATORS Application filed July 17,

This invention relates to a mounting for the radiator of motor vehicles and more par- 'ticularly trucks in which the radiators are subjected to very heavy vibrations and shocks.

7 It is the object of this invention to provide a mounting for this purpose whereby any weaving or vibration inthe main frame or chassis of the car will not be transmitted to the radiator and cause leakage in the latter; also to provide a mounting for radiators which permits of quickly assembling the parts for use and disassembling the same for repairs; also to permit of taking down and putting up the parts for effecting repairs without destroying any parts of the radiator or mounting and without requiring the replacement of any parts.

In the accompanying drawings:

- Similar characters of reference indicate like parts in the several figures. o

The radiator may be of any suitable and well known construction that, for example, which is shown in the drawings, consisting of a central cellularcore 10 provided with a plurality of water passages and a plurality of air passages intercalated with said water passages, an upper water tank or box 11 which communicates on its underside with the upper ends of said water passages and a lower water tank or box 12 which communicates on its 1926. Serial No. 123,076.

upper side with the lower ends of said water passages. On the central part of the upper water tank the same is provided with an inlet nipple 13 and one of the lower corners of the lower water tank is provided with an outlet nipple 14, which nipples are adapted to be connected with the water circulating system of the gas engine which serves as the power unit for driving the auto. Projecting upwardly from the central parts of the top of the upper tank is an upright filling neck 15 and top of the shell, and supporting lugs 24 projecting laterally from the side walls 18, 19 and adapted to be detachably secured by bolts or otherwise to the longitudinal bars 25 of the frame forming parts of the chassis of the car. The parts of the shell just described are preferably formed integrally by casting of metal such as aluminum.

The improved means for removably mount ing the radiator within this shell in accordance with my invention are constructed as follows:

Arranged horizontally and lengthwise below the lower water tank is a stud bar 26 which is provided at its opposite ends with upwardly projecting arms 27, 27, arranged alongside of the ends of the lower water tank and the lower end parts of the core. On its upper side the stud bar is provided with a lower channel shaped retaining clip which receives the central part of the lower water tank and which has its horizontal web 28 spot welded to the top of the stud bar and its upright flanges 29 soldered to the front and rear walls of the lower tank. In order to avoid any squeaks in the joint between the v stud bar and the radiator due to Vibration when the car is running a strip of canvas or other anti-squeak material is placed between the underside of the lower tank and the top of the web 28 of the lower retaining clip. Each of the arms of the stud bar carries an upright side clip or side wall which has a web 31 secured by spot welding to the inner side of the respectivestud bar arm and twoinwardly projecting flanges 32,32 which embrace the adjacent upright edge portion of the core. Secured to opposite ends of'the upper tank and extending downwardly along opposite upper edge portions of the core are two metal straps 33, 33 which are connected with the upper tank by soldering and detachably connected withthe side walls or clips by bolts 34 passing through laterally eXtending flanges 35 arranged on the upper ends of the webs 31 and the lower ends of the straps, as shown in Fig; 3.- Each of the straps is preferably provided with a few corrugations 38 in order to render the same somewhat elastic and permit the; same to yield when subjected to strain. 7 Between the underside of, the stud bar and the bottom of the shell is arranged an antiesqueak pad 37 of woven fabric, canvas or the like which effectively cushions the parts relatively to each other and prevents any squeaking noise .due to shifting of parts. relatively to; one another when the car is in operation. 'The stud bar is detachably connected with, the bottom of the shell by two 'fastenings which are arranged on opposite sides of the center of the radiator and as these fastenings are alike in construction the following, description of one'will apply to both. I

Extending forwardly'from the, rear edge of the bottom of the'shell-is a horizontal slot ,38the closed frontendof which is'surrounded by an upwardly extendingcounter sunk seat 39 which is preferably of circularforni. For

the purpose of straightening this slotted part of the shell bottom a downwardly deflected bridge 40 preferably connects those-parts of the shell bottom'on opposite sides of the rear or open end of the slot 38. Projecting downwardly from the stud bar is astud bolt, 41 which has its upper headed end preferably 7 brazed or welded to the bar While its lower threaded end passes throughthe anti-squeak pad 37 and through the slot 38 inthe shell bottom at the front end-thereof. The stud bar is securely held against vertical and horizontal displacement on the shell bottom by a retaining ring 42 surrounding the stud bolt and engaging with the counter sunk seat 39,

a split spring or lock washer 43 engaging with the underside of the retaining washer, and a clamping screw nut 44 applied to said stud bolt 41 and bearing against the underside of the lock washer. VVhenbothof these fastening means are thus applied to the lower part of the radiator core and the bottom of the shell the radiator is not only heldfirmly against the bottom but also prevented from moving horizontally inasmuch as the re taining ring 42 which engages the counter' sunk seat 39 prevents such movement. When however it is desired toiremovethe radiator from theshell it is only necessary to slacken I the clamping nuts 44 enough to permlt the retaining rings to drop out of the seats-39 after which the stud bolts and the 'rings, washers and nuts mounted thereon may be moved rearwardly out of slot 38 and through the bridges 40 while the lower part of the the same is provided with an upwardly pro= jecting tubular neck 45 which receives the filling tube 15 of the radiator. lf'rcushioned Joint is formed between this neck and the filling tube by an elastic grommet or ring 46 surrounding the filling tube within the neck 7 V and bearing with its conical underside 461 against an upwardly facing conical shoulder 47 on-the interior of the neck, and a clamping ring 48 having a screw connectionwith said neck and bearing with its lower conical end 49 against the upper conical side 5Ov of the grommet, whereby the latter is compressed and caused to fit'tightly bet-ween the filling tube and neck and prevent the same from rattling when the car is in motion.

When assembling the radiator and the shell the upper part of the radiator is first moved forwardly into the upper part of the shell and then moved upwardly'so as to pass the filling tube through the tubular neck from the inner to the outer end thereof and at the same time the lower part of the; radiator and associated parts are moved forwardly into the lower part of the casing and the stud bolts are moved forwardly intothe slots 38.

The screw nuts 44 are now tightenedso as to force-the retainingrings 42 into their seats and draw the stud bar down'againstthe antisqueak pad on the bottom of the shell. The grommet is also slipped over the filling tube and forced downwardly between the same, andthe tubular neck by applying the clamp ing ring 48 to the neck and producing a tight fit between the grommet, neck andfiller tube.

When thus assembled the radiator is sup ported at practically three'points on the shell, that. is to say," by the two stud bolts near opposite ends of its lower part and by the filling tube on the central upper part thereof, while'the remaining parts of the radiator are out of engagement with the shell. Due to this.

mounting of theradiator, anyfweaving action or strains towhich the shell may be subjected while in use will not be transmitted to the radiator inasmuch as the filling-tubeof the radiator will slide lengthwise in the neck during any relative movement of the shell andllo radiator, thereby preventing any leaks in the latter and avoiding the necessity of frequent repairs. If, however, any extensive repairs of the radiator become necessary at any time which requires the removal of the radiator from the shell this can be easily accomplished y simply loosening the clamping nuts ist on the stud bolts and removing the clamping ring from the tubular neck, when the parts may be readily dismembered. It is, therefore, possible to readily remove the radiator from the shell and restore the same without destroying any parts or making any replacements while effecting such removal out of and restoration of the core into the shell.

The diameter of each seat 39 and the retaining ring f?) seated therein is larger than the width of the slot 38 which accounts for this ring andthe stud bolt ll within this ring not being locked in position on the bottom of the shell when the screw nuts 44. are tightened.
